To all whom it may concern: 1

Be it known that I, HUGH WARREN 'LEE,-a I subjectof the King of -GreatBritain, residing at Elswick Works, Newcastle-upon- Tyne, England, haveinvented a new and useful Improvement in Pedestal Gun-Mountings, ofwhich the following is a specifica- This invention relates to gunmountings and has for its object the provision of a mounting. whereinthe gun may be given a large movement in elevation without at the end ofits recoil fouling the pedestal or a ring of rollers of relatively smalldiameter carried by the pedestal and upon which the mounting ispreferably supported. For the purposes of this specification the termpedestal shall be considered to include the ring of rollers carried byit.

According to this invention, the bearings supporting the trunnions ofthe cradle in which the gun recoils are slidably mounted on girdersarranged above the pedestal and means are provided for moving thebearings upon the girders. Means for connecting the cradle to thegirders and for preventing the gun on recolling from fouling thepedestal or the ring of rollers upon it are also provided. The means forconnecting the cradle to the irders and for preventing the gun fromfouling the pedestal may consist of lugs on the cradle having slots intowhich bolts on the girders enter. The positions of the lugs on thecradle in relation to the trunnions and of the bolts in relation to thepedestal are such that the breech of the gun on recoiling clears thepedestal.

The annexed drawings illustrate a gun upon a mountin made in accordancewith this invention. Figure 1 is a side elevation partly in sectionshowing the gun at an angle of 25, and Fig. 2 1s a section on the line22, Fig. 1. Fig. 3 is an elevation partly in section in which the gun isat an angle of 50. Fig. 4 is an end elevation partly in section.

A gun 1 is carried in a cradle 2 having trunnions 3 supported inbearings 4 slidably mounted on girders 5 supported by rollers 6 carriedon a fixed pedestal 7. The bearings 4 are connected by pins 8 to screws9 on which are nuts 10 carried in brackets 100 and adapted to be rotatedthrough worm gearing 11 (see Fig. 4) by a hand wheel 12;

on the cradle 2 are lugs 13 having slots 14 to receive bolts 15 slidingin brackets 16 on the girders 5. The bolts 15 are operated by levers 17pivoted at 18 to the girders 5; one end of each lever 17 engages withthe bolt 15 while the other is piv'otally-secured to a nut 19 on a shaft20 rotated by a hand wheel 21. On the radle 2is an are 22 gearing with apinion 23 mounted on one of the trunnion bearings 4 and operated by ahand wheel 24.

When it is desired to alter the elevation of the gun, the handwheel 12is turned, rotating the nuts in brackets 10 and actuating the screws 9so that the bearings 4 slide upon the girders 5. As the bolts 15 are inengagement with the slots 14 in the lugs 13, the gun is elevated ordepressed according to the direction in which the wheel 12 is turned.

When it is desired to bring the gun into a horizontal position for thepurposes of loading without disturbing the setting, the bolts 15 arewithdrawn from the slots 14 and the hand wheel 24 is rotated, turningthe pinion 23 gearing with the are 22, thus moving the cradle and thegun. The gun may be returned to its former setting by turning the handwheel 24 in the reverse direction until the slots 14 are in registerwith the bolts 15.

The gun is trained by turning the mountin upon the rollers 6.

I Vhat I claim is 1. In a pedestal gun mounting, girder mounted abovethe pedestal, a cradle carrying the gun, trunnions on the cradle,bearings supporting the trunnions and slidably mounted on the girders,screws secured to the bearings, nuts mounted on the girders and engagingwith the screws, means for actuating the nuts and means for connectingthe cradle to the girders and for preventing the 1gun on recoiling fromfouling the pedesta 2. In a pedestal gun mounting, girders mounted abovethe pedestal, a cradle carrying the gun, trunnions on the cradle,bearings supporting the trunnions and slidably mounted on the girders,means for moving the bearings, lugs on the cradle, slots in the lugs,bolts carried by the girders and adapted to enter the slots and meansfor actuating the bolts.

3. In a pedestal gun mounting, girders mounted above the pedestal, acradle carrying the gun,trunnions on thecradle, bearings supporting thetrunnions and slidably mounted on the girders, screws secured to thebearings, nuts mounted on the girders and engaging with the screws,means for actuating the nuts, lugs on the cradle, slots in" the lugs,

bolts carried by the girders and adapted to the hollow pedestal andhaving a part projecting beyond the pedestal adapted to support the gunwhen fired at low elevations, a frame supported by and movable along thegirder, a cradle trunnioned in the frame,

means for moving the frame along the girder and means for elevating thecradle.

5. In a gun mounting, a hollow pedestal, a horizontal girder rotatablymounted upon the hollow pedestal and havinga part projecting beyond theedestal adapted to support the gun when Ered at low elevations, a framesupported by and movable along the girder, a cradle trunnioned in theframe, screws secured to the frame, nuts mounted on the irder andengaging with the screws, means or actuating the nuts, and means forelevating thecradle.
